Attribute for <FRAMESET ...>
BORDERCOLOR = color expression

BORDERCOLOR sets the color of the borders in the frameset.

this code	produces this
<FRAMESET ROWS="50%,*" BORDERCOLOR=RED> <FRAME SRC="fsbctitle.html"> <FRAME SRC="fsbcmain.html"> <NOFRAMES>NOFRAMES stuff </NOFRAMES> </FRAMESET>	this page

There is no defined behaviour if you use BORDERCOLOR in both <FRAMESET ...> and <FRAME ...>. Different versions of MSIE resolve the situation differently. Netscape is a more consistent. In Netscape, <FRAMESET BORDERCOLOR="..."> sets the color for all borders, and <FRAME BORDERCOLOR="..."> makes exceptions to that rule. For example, this code sets the borders for all frames to yellow for the borders of the middle frame which are red:

this code	produces this
<FRAMESET ROWS="*,*,50%,*,*" BORDERCOLOR=YELLOW> <FRAME SRC="fsbcex1.html"> <FRAME SRC="fsbcex2.html"> <FRAME SRC="fsbcexmain.html" BORDERCOLOR=RED> <FRAME SRC="fsbcex3.html"> <FRAME SRC="fsbcex4.html"> <NOFRAMES>NOFRAMES stuff </NOFRAMES> </FRAMESET>	this page
